## Population density

United Kingdom is 8.2 times more densely populated than United States — 285 against 35 people per km².

## Practical differences

- They drive on opposite sides — United Kingdom on the left, United States on the right.
- Different currencies: the British pound and the United States dollar.
- United States spans 6 time zones, so "local time" there is not a single answer.
- Different continents — Europe and North America.

## United Kingdom

Made up of Great Britain, the north-east of Ireland and around 6,000 smaller islands. No point in the UK is more than about 113 km from the sea. Ben Nevis, the highest point, is 1,345 m, which is modest — but the country has around 31,000 km of coastline once every inlet is counted.

## United States

Third or fourth largest country in the world depending on how China's area is counted. It spans six standard time zones across the fifty states, from UTC-10 in Hawaii to UTC-5 on the east coast. Death Valley holds the highest reliably recorded air temperature on Earth, 56.7 °C in 1913, and is 86 m below sea level; Denali, 5,500 km away in Alaska, is 6,190 m.
